NAME
Gentoo::Dependency::AST - Convert a canonicalized (R|P|)DEPEND into an
Abstract Syntax Tree
VERSION
version 0.001000
SYNOPSIS
Those familiar with Gentoo's "ebuild" format will be aware there are
several variables that contain strings of dependencies that are
required.
Namely: "PDEPEND" , "RDEPEND" and "DEPEND"
If you're a "paludis" user, one can get the canonicalized versions of
these variables via
cave show -c =cat/pkg-version
This module exists to parse those strings and provide a structured graph
representing the dependencies:
use Gentoo::Dependency::AST;
my $node = Gentoo::Dependency::AST->parse_dep_string( $string_from_portage );
METHODS
"parse_dep_string"
$class->parse_dep_string( $string ) # returns Gentoo::Dependency::AST::Node of some kind
